Peak season utility driver? Tell me ALL about it

I drive Sat. Air out of the W.Sac. Hub and was hoping to find someone here who had driven "peak season" as a utility driver. Anyone out there with feedback about this job and what it is all about? Most I know prefer to stay in the operation and work double shifts during the peak season because they make more money than driving. I am #10 on the list for peak season utility driver but no one seems to know when it starts or what the job is really all about. Can anyone out there(here) provide some insight into this position?? Any info. would be much appreciated! :confused:1
